Allowed: Sellers can only sell up to a maximum of $100 value in coupons or 25 valid, unexpired, original coupons per month, whichever limit is reached first. (The 25 coupons limit includes multiple coupons purchased from a multi-quantity listing.)
Not allowed: Coupons for “free” products-including coupons where the coupon holder buys some quantity of items at one price and gets some number of items for free, for example, “buy-get-one-free” offers, or offers for free shipping-may no longer be sold on eBay.
Starting September 1, 2013, listings for these coupons that don’t comply with these policy changes will be removed. After September 1, listings in violation of this policy may be subject to a range of other actions, including restrictions of buying and selling privileges and a suspension of your account.
I think this change is great, though. Getting rid of all free-product coupons and Buy One Get One Free offers will eliminate a huge percentage of the counterfeits being sold on the site. And, restricting sellers to a total of $100 in value or 25 total coupons per month will reduce Ebay coupon resale to a “hobby,” not a viable business model.
